Weighing system
of loader (forklift scale) is a kind of loader weighinge quipment , also known as loader scale, forklift truck electronic scale, which is integrated with loading machine control part , and weighing when loader operated. Load Scale can also be used for the measurement of vehicleload, limit load and earthwork . it is composed of the sensor and the weighing instrument etc., dynamic or static measurement are both can weighed. You can store , print and automatic total by weighing instrument, it does not affect normal load, and it can be installed in various types of loading machine from Chinese or other cuuntries.
Used and Occasion
The loader weighing system for loading machine and forklift is applicable to automatic weighing , overload protection and workload management. it can weigh coal,coke, non-ferrous metal ore, granite, marble, earthwork , sand , stone, brick, industrial or civil building, mining waste material andadditive etc.
The weighing system of loader is widely used in mining , ports, factories, storehouses, buildings and railway transport of goods loading system.
Working Principle
The wighting system is based on two pressure sensors which one is in the loader arm oil inlet cylinder and another is in return oil circuit,to measure the change of cylinder pressure when loader boom is lifting,and compensated for speed,weighing instrument can automatically calculated,then obtain the weight data and display the weight on instrument display,and automatictly add up.
System Components
1.Two pressure senor,which is used to measure pressure changer from loading machinehydraulic system.
2.A group of position sensor, to collect pressure data when position sensor to detect the boom lifting the specified location.
3Weighing instrument,to calculate weighing data, and shows weighing results.
